Specification of Letters Patent.

Patented Mar. 31, 1914:-

Application filed September 6, 1912. Serial No. 718,899.

To all whom it may concern:

Be it known that I, AMos D. HOLT, a cit-1- zen of the United States of America, an resident of Hopkinton, Middlesex and State of Massachusetts,have invented certain new and useful Improvements in Machines for Transferring Packaging-Receptacles, of which the following is a full, clear, and exact description.

This invention relates to machines for receiving boxes or cartons of any desired shape or form and to transfer them to a position to be filled, and then advance them to a position to be removed, and at the same time bring other boxes to the filling position.

One of the objects of the invention is to provide a transferrin device in the form of a turret 0r turn-table, having a series of means to grip the boxes at a certain position as the turret is intermittently advanced for a distance equal to the distance apart of the gripping means, the grippers automatically closing on the box as presented, and upon the box being so held and advanced to another position the gripping means will automatically release the box, between which two positions in the orbit of travel of the grippers and box, and at which place the box is brought to rest, the box can be filled with any desired material.

A further object of the invention is to provide means for automatically advancing the torrent member step by step to bring the grippers successively to said positions, and to insure the turret being retained in such positions during the filling operation.

In the accompanying drawings representing one embodiment of my invention Figure 1 is a plan view; Fig. 2 is a side elevation.

The turret denoted generally by 6 consists of a head 7 secured to a shaft 8 rotatable in a bearing block 9 that is fast at the upper end of a sleeve 10; this sleeve is suitably supported at its lower end in a base member 11 through a bearing block 12, which latter forms a bearing for the lower portion of the shaft 8 which is inclosed by the sleeve 10. a

The turret is provided with a series of gripper members, four being shown, a quadrant distance apart; and each is shown as comprising a stationary jaw which is fixed in the county of,

to the head, and an opposite jaw which is movable relatively to the fixed jaw.

On the head 7 which has four arms 15 is secured a piece 16 to which the jaw members 17 are secured, one at each of the four said positions, and equi-distant from the axis of the turret.

Each of the arms 15 has pivoted thereto a lever 18 at the hinge 19, which latter carries a movable jaw 20, the jaws 17 and 20 extending substantially vertical, and are preferably parallel when closed on a box by the swinging of the arm 18. For the purpose of swinging these four levers 18, each has an arm 21 which is connected by a link 22 with a lever 23 pivoted on each of the arms 15 of the head. The other end of these levers carries a roller 21 so that when the lever is swung it may engage a cam member 25 fast on the bearing block 9; and each of these levers 23 is connected by a coil spring 26 with the middle portion of the lever 18 whereby the levers 23 will be swung to press the roller 24: against the cam, and which movement will move the jaw 20 toward the jaw 17.

The cam member 25 being fast to the bearing block 9, will not partake of the rotation of the head carrying the pairs of jaws and levers connected therewith, consequently upon rotation of the head by the shaft 8 the levers 23 will have the roller portion move around to the periphery of the cam 25. Since there are four of these gripper members provided on the turret, upon swinging the turret through an arc of 90 degrees, each gripper member will be advanced to bring the succeeding member to the same position; and, as shown, the gripper members are actuated through this cam whereby they are held open at a certain position; then as the head advances the grippers at once close and remain closed until such gripper is moved through half a revolution, at which position they are opened, permitting the box to be removed; but during such movement of the turret when it has advanced a quarter turn, the next gripper will be brought to the osition just occupied by a gripper and will be caused to close, so that at each advance of a quarter turn, one of the-grippers will be caused to close and the one then on the opposite side of the turret will be caused to open.

r the form At the intermediate position in the advance of the grippers, the then closed gripper will hold a box, and at this position the box can be conveniently filled; and consequently the turret will be intermittently advanced for a quarter of a revolution and then arrested to have the box filled at the filling position; and for this purpose the cam 25 isshown as provided with a portion at 30 permitting the lever 23 to be swung by the spring to close the jaw member 20, the cam as the lever'is advanced permitting the jaw to be held closed on the box by the spring until the box is carried past the position of filling and approaches the position to be removed, that is opposite the position at which the boxes are supplied, the cam having a rise at 31 which will swing the lever 23 and cause the jaw 20 to move away from the jaw 17 to release the boxes.

The position for receiving the boxes is indicated by 33 in Fig.1, and the position for having the box removed is at 34 on the opposite side, while at the intermediate position 35 the box can be conveniently filled.

As stated, the jaw members 17 and 20 are substantially vertical, and, therefore, engage only the two opposite sides of a box.

Between the vided a suitable support for the bottom of the box, such as circular track members in of bars 36 and 37 carried by radial arms 38 extending out from the stationary head 9.

If desired, suitable conveying means may also be arranged to feed the box into the grippers at the positions 33, and to remove the box when brought tothe position at 34;

part of such conveying means being shown as comprising a suitably supported wheel 40 around which travels a conveyer belt 41 avliich will serve, when advanced, to bring a box to the turret between the jaws 20 and 17 at the position 33, a suitable track 42 being provided below the gripper jaws, and a suitable stop 43 being arranged beyond the jaws at each set of jaws to limit the movement of the box, the track 42 being below the path of movement of the jaws so as not to interfere therewith.

At the opposite side of the turret at the position 34, a moving belt 44 may be provided, passing around a pulley45 suit-ably supported; and the track members 36 and 37 have their top edges at one end adjacent the track 42 to engage the bottom of the box, and at the other end of these tracks 36 and 37 they will serve to properly guide the box onto the belt 44. By this arrangement it Gopies of this patent may be obtained for five cents each, by addressing the Washington, I). 0.

positions 33 and 34 are procause the jaws carry the box around to the position at 34 r and thereupon open, the belt 44 will serve to remove the box from the turret; it being understood that any desired or suitable form of conveying means 3 ing the boxes may be employed.

1. In a box transfer machine, the combination of a rotatable turret, a series of box grippers mounted on the turret, each comprising a pair of horizontally opposed jaws, one jaw in each pair being pivoted to move to and from the other jaw, a stationary cam, a set of levers pivoted on the turret to engage said cam as the turret is swung, a link connecting each lever with one said jaw, a spring connecting each lever with the turret to hold the lever engaging the cam, said cam being shaped to cause the jaws to open at one part of the orbit of the turret, and to cause the jaws to close at another part of the swing of the turret, and to remain closeduntil the jaws reach the said place on opening.

2.111 a box transfer machine, the combination of a rotatable turret, a series of box grippers mounted on the turret, each comprising a pair of horizontally opposed jaws, one jaw in each pair being pivoted to move to and from the other jaw, a stationary cam, a set of levers pivoted on the turret to engage said cam as the turret is swung, a link connecting each lever with one said jaw, a spring connecting each lever with the turret tohold the lever engaging the cam, said cam being shaped to cause the jaws to open at one part of the orbit of the turret, and to to close at another part of the turret, and to remain closed until the jaws reach the said place of opening, a support for articles at the place of opening of the aws, a conveyer arranged to feed articles in a radial direction to the said support and into the jaws, and a second conveyer at the place of opening of the jaws arranged to receive the articles as released from the jaws to remove the articles in a radial direction from the machine.
